[1] We use geodetic studies to quantify several cases of significant asymmetry in interseismic and coseismic effects along large continental strike-slip faults using simple two-dimensional edge dislocation models. We first show that asymmetric elastic loading characterizes the present Main Marmara Fault, a portion of the North Anatolian Fault along the northern margin of the Sea of Marmara. The...

On the 4 th of June, 2000 and 12 September, 2007, Ratu Agung Sub-district, Indonesia experienced significant damage due to liquefaction after earthquakes. Therefore, this study aims determine Liquefaction Potential Index in area. Data shear wave velocity (Vs) was collected using Multichannel Analysis Surface Wave (MASW) method. The measurement location set up on a grid 32 observations points wi...

A supercritical hydrogen liquefaction cycle is proposed and analyzed numerically. If hydrogen is to be used as an energy carrier, the efficiency of liquefaction will become increasingly important. By examining some difficulties of commonly used industrial liquefaction cycles, several changes are suggested and a readily scalable, supercritical, helium-cooled hydrogen liquefaction cycle is propos...

On February 27, 2010, the central-south part of Chile was affected by a strong ground motion of Magnitude 8.8, that induced moderate values of peak ground acceleration (PGA) on rock outcrops, in the range of 0.13g to 0.32g, while in soil deposits, a maximum PGA of 0.94g was recorded. The duration of the shaking was close to two minutes as it is substantiated by the available acceleration record...

Coseismic displacements play a significant role in characterizing earthquake causative faults and understanding earthquake dynamics. They are typically measured from InSAR using preand post-earthquake images. The displacement map produced by InSAR may contain missing coseismic values due to the decorrelation of ASAR images. This study focused on interpolating missing values in the coseismic dis...

Soil liquefaction has been extensively investigated over the years with the aim to understand its fundamental mechanism and successfully remediate it. Despite the multi-directional nature of earthquakes, the vertical seismic component is largely neglected, as it is traditionally considered to be of much lower amplitude than the components in the horizontal plane. The 2010-2011 Canterbury earthq...

Paul C. Rizzo Associates, Inc. (RIZZO) has developed efficient computational tools to evaluate the liquefaction potential of earth embankment dams located within high risk seismic regions. Two relevant case histories are the Saluda Dam and the Santee Cooper East Dam Extension, both structures susceptible to liquefaction, and located in South Carolina. Saluda Dam presents liquefaction risks with...

We determine coseismic and the first-month postseismic deformation associated with the Sumatra–Andaman earthquake of 26 December 2004 from nearfield Global Positioning System (GPS) surveys in northwestern Sumatra and along the Nicobar-Andaman islands, continuous and campaign GPS measurements from Thailand and Malaysia, and in situ and remotely sensed observations of the vertical motion of coral...

Megathrust earthquakes rupture a broad zone of the subducting plate interface in both along-strike and along-dip directions. The along-dip rupture characteristics of megathrust events, e.g., their slip and energy radiation distribution, reflect depth-varying frictional properties of the slab interface. Here, we report high-resolution frequency-dependent seismic radiation of the four largest meg...

Coseismic slip is observed to increase with earthquake rupture length for lengths far beyond the length scale set by the seismogenic layer. The observation, when interpreted within the realm of static dislocation theory and the imposed limit that slip be confined to the seismogenic layer, implies that earthquake stress drop increases as a function of rupture length for large earthquakes and, he...
